Investment of $3000 at 16% simple interest for 2 years
Investment of $3000 at 5% simple interest for 20 years
Investment of $1000 at 16% simple interest for 20 years
Solution:
(1) Investment of $3000 at 5% simple interest for 20 years
Simple interest 1 = $3000
(2) Investment of $3000 at 16% simple interest for 2 years
Simple interest 1 = $960
(3) Investment of $1000 at 16% simple interest for 20 years
Simple interest 1 = $3200
Order from least interest amount to greatest interest amount:
$960 < $3000 < $3200
Investment of $3000 at 16% simple interest for 2 years
Investment of $3000 at 5% simple interest for 20 years
Investment of $1000 at 16% simple interest for 20 years
Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
